I worked at a Honda dealership for several years and have been using their phosphate-free coolant that they sell currently. When I checked it against the VW bottle the first eight or so ingredients were the same and in the same order. I've used it for at least 7 years and almost 100,000 miles with no issues.

Subject: replacements for phosphate-free coolant

 
 
 
It appears that it's no longer possible to buy phosphate-free coolant, at 
least in Canada.  VW no longer carries it.  They say that their "aluminum 
core compatible" coolant is a suitable replacement.  My mechanic said 
something similar. 
 
What do folks here think?
